3 Description
The TPS3899-Q1 is a nano-power, precision voltage
supervisor with ±0.5% threshold accuracy and
programmable sense and reset time delay in a 6-pin
space saving 1.5mm × 1.5mm WSON package. The
TPS3899-Q1 is a feature-rich voltage supervisor that
offers the smallest total solution size in its class. Builtin
hysteresis along with programmable delay prevent
false reset signals when monitoring a voltage rail or
push button signals.
The separate VDD and SENSE pins allow for
the redundancy sought by high-reliability systems.
SENSE is decoupled from VDD and can monitor rail
voltages other than VDD. Optional use of external
resistors are supported by the high impedance input
of the SENSE pin. Both CTS and CTR provide delay
adjustability on the rising and falling edges of the
RESET signals. CTS also functions as a debouncer
by ignoring voltage glitches on the monitored voltage
rails and operates as a "manual reset" that can be
used to force a system reset.
The precision performance, best in-class features in
a compact form factor, makes the TPS3899-Q1 an
ideal solution for wide ranging automotive and batterypowered
/ low-power applications. The device is fully
specified over a temperature range of
–40°C to +125°C (TA).
